Beeps can sometimes be felt

You can blame an evolutionary fault if you can't concentrate while listening to the unpleasant sound of a truck backing up. Natural sounds are created by the passage of energy (for example, a stick striking a drum) and fade over time, and our perceptual system has evolved to use sound decay to determine what formed it and where it came from. Our brains, on the other hand, struggle to keep up with beeps because they rarely change or fade out over time.

Attractivity

"Don't judge a book by its cover," we say, but our brains are notorious for doing just that. Even if we don't know it, a single favourable attribute in a person might fool our brain into thinking the person has numerous favourable characteristics. The "Halo effect" is the name for this phenomenon. We may automatically think that someone who is visually appealing is educated, pleasant, amusing, and so on. Because this is by far the most common form of the phenomena, the "Halo effect" is known as "the physical attractiveness stereotype." This is relevant to celebrities and why we believe we "know" them even when we don't.

Doorway

How many of you have entered a room with a specific aim in mind, only to forget about it? The doors, it turns out, are the source of the strange memory lapses. According to University of Notre Dame experts, passing through a doorway activates an event boundary in the mind, which separates one set of thoughts and memories from the next. The notions from the previous room are filed away, and a blank slate is prepared for the following one.

Remember that bad meal you had?

Your brain is to blame if you've ever questioned why a single terrible experience may dramatically affect your life. A single negative dinner experience, for example, may tarnish the flavour of that dish in your mind, even if you enjoy it. The Garcia Effect is named after a scientist named Dr John Garcia, who studied it on rats. If a meal makes you feel sick or queasy, you'll probably develop a taste aversion to it. Even if you like the meal, this makes your brain wary of eating it again. 

Being on a cliff's edge

When people reach a certain height, especially for the first time, they often feel a strange sense of detachment. This is known as the "breakaway phenomenon." You feel disconnected from the earth, literally, even if you're in a building or on an aeroplane,” says Dr James Giordano, a neurology and biochemistry professor at Georgetown University Medical Center. This sensation is most commonly felt while flying, but it can also be felt while standing on a balcony or at the top of a tall building.

This sensation has nothing to do with a fear of heights and can make some people feel extremely calm and peaceful. Dr Giordano explains, “Some people enjoy the sensation, while others find it unsettling.”
